Relative and Absolute Age Dating
Start studying Geology: Relative Dating, Fossils, and Radiometric Dating. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Explain the difference between relative and absolute dating of earth materials. * relative dating- placing rocks & events in their proper sequence *absolute/ numerical dating- specifying actual # of yrs that passed since an event occurred; done by radiometric dating. List and briefly explain, the tools used in relative dating. Radiometric Dating. a method of determining the absolute age of an object by comparing the relative percentages of a radioactive (parent) isotope and a stable (daughter) isotope. Isotope. atoms of the same element that have different numbers of neutrons. Radioactive Isotopes. Atoms that are unstable, meaning they decay.

Example: Phanerozoic. Relative Dating. Definition: Method determining the age of a fossil past comparing its location with that of fossils in other rock layers. Radiometric Dating. Definition: A method of determining the age of a fossil beside relying on radioactive isotopes, which deterioration, or break on skid row, into stable isotopes at a. Perfect Dating. determining an approximate computed period in archaeology and geology. Some scientists prefer the terms chronometric or date-book dating, as utilization of the direction "absolute" implies an unwarranted certainty and precision. Absolute dating provides a computed numerical age in contrast with interconnected dating which.
